42-acre lake in Thunder Bay District, Ontario. The lake tops out around 38 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 43 acres, worked by 1.4 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. 37% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 0.6 mi with a 0.2-mi widest point. It sits in Thunder Bay District. Loch Erne sits 1 mi south — the closest neighbouring chart.
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 17 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
